RACE WALKING POSTURE
Looking into the distance, with the shoulders dropped to open your rib cage, the trunk straight, not leaning too far forward, nor too far back: that's the upper body posture for race walking.
The arms are bent at a 90° angle and make large movements backwards and forwards. This swinging movement stays close to the body and follows the walker's axis. Hands are relaxed.
As for the lower body, the knee is blocked when the foot hits the ground. Race walking requires one foot to be in constant contact with the ground. To do this, as one foot pushes off, the other foot hits the ground. The foot rolls from the heel to the toes, creating a dynamic movement which increases propulsion.
The pelvis is mobile, causing the hips to sway and giving the legs a flowing forward movement. Increasing frequency is more effective for increasing speed than lengthening the stride.
